(S)TH403 – 424 60Hz – Closed impellers
Immersion Pumps series TH and FH use closed impellers in order to minimize power consumption and to optimize hydraulic pump efficencies. In addition, the TH series offers high pressures at short immersion depths. Inline pumps of the series FH can be used as boosting pumps if provided with positive inlet pressure. This inlet pressure can be provided by the central coolant supply or a feed pump. In such a setup, pumps of the series FH can raise the incoming pressure by up to 26 bar.
Extended length is possible. See mechanical/hydraulic features within the technical information section.
